There is no signal when the TV is connected to WIFI. The possible causes and solutions are as follows:
1, first check whether there is a problem with the Internet, use the mobile phone to connect the wireless try, if not, find the network after-sales service;
2, what brand is the TV, is not the manufacturer's network there is a problem, you can contact the TV after-sales customer service;
3, the TV is pure network TV, or to connect the cable signal to watch TV, you need to know the model;
4, when they can not solve the above problems, or find the TV after-sales customer service over.
This is normal for two main reasons:
1, your smart TV connection to the resource speed is slow, even if there is 50 megabytes of broadband, but the input source is slow, broadband how fast is useless.
2, your WiFi output or smart TV to receive the WiFi signal is not good, it is recommended to put the router closer or directly connect the network cable without wireless, because the wireless signal is often easily affected, and the network cable will not. If the above two methods do not work, it is recommended to contact the smart TV customer service.
